Re: CRT based RPTV Convergence Repairs
Hey there Sasquachh. I have the same model tv, and i just did my repair about a month ago. One advice, as you remove the harnesses one-by-one, its a good idea to number them, and then draw an approximate location on a piece of paper. I used masking tape and a sharpie. Basically, a rough layout of the location of the harnesses on the board. The harnesses are numbered, but the numbers on the board are not easily visible, and a layout on paper will help guide you when you're putting them back. Pretty much all wire-ties will have to be undone. Do not force the wires out, and always hold the connector, not the wires. When you have removed the assembly completely, be sure to carefully dust it off with some compressed air for electronics. Do this away from the tv set and preferably not inside your house. You can get a can from radio shack or a similar store. And while you're there, pick up a little tube of thermal paste. You'll need it for the new chip.
The center board will have to be removed from the frame. Be careful when you handle the board after you've unscrewed it. I used a piece of cardboard on the table, then flipped the board over and de-soldered the chip. After you have removed the chip, the resistors can be tested.
I am giving you some hints as I assume you have not done anything similar before. Pardon my ignorance if I offend you. Sorry, I did not take pictures, my camera's memory card has been acting up.
So, take your time, and good luck!
